附 录 翻译原文 Experimental study on visibility of exit signs in buildings L.T. Wong, K.C. Lo Department of Building Services Engineering, The Hong Kong Polytechnic University, Hong Kong, China Received 26 November 2003; received in revised form 19 January 2006; accepted 23 February 2006 Abstract： Visibility of exit signs in terms of the height of the sign content was studied experimentally in an 18m internal corridor. Four factors affecting the visibility including graphics, colours, lighting conditions and ages of the observers were investigated. Combinations of designations containing the English and Chinese words EXIT, five directional indicators and two exit symbols in different colours under normal and emergency lighting conditions were presented to 30 observers of different age groups to determine their visibility. The sign heights detected, identified and identified with confidence were measured. Increased height for correct identification was found for an exit sign containing two symbols as compared to a sign containing only one symbol. A green exit sign was reported to be highly visible. It was also reported that at reduced illumination, the sign height for correct identification increased. ? 2006 Elsevier Ltd. All rights reserved. 1. Introduction Emergency exit signs are installed to provide markings of exits and escape routes in buildings and should be able to assist the occupants to leave the buildings effectively in case of emergency [1,2]. Exit sign is an essential installation in buildings and the specifications are stated in design guides and regulations [3–6]. Thousands of exit signs can be found in many high-rise buildings. In Hong Kong, exit signs containing the word EXIT in English and Chinese of not less than 125mm height are specified for local buildings [5,6]. A sign shall be designed with a combination of directional indicator, symbol and words: while the general design shall follow the standard specified [4], the Chinese word shall reach a mi
